Victron Energy SmartSolar MPPT 100/30 Solar Charge Controller 12/24V 30A

Harness the sun with the Victron Energy SmartSolar MPPT 100/30 — an ultra-fast solar charge controller designed to optimise your energy harvest with built-in Bluetooth, 30A output, and advanced MPPT tracking that handles partial shading conditions exceptionally well.

Benefits:

• Built-in Bluetooth — monitor battery voltage, solar history and load output from your phone

• 30A charge current — suits panels up to 430W at 12V or 860W at 24V

• 100V maximum PV input — flexible panel wiring options

• Up to 30% more energy than PWM controllers in variable light

• Configurable charge algorithms via VictronConnect — day/night timing, light dimming, load control

• BatteryLife algorithm protects battery from repeated deep discharge

• Compatible with 12V and 24V battery banks

Features:

The SmartSolar MPPT 100/30 sits between the 100/20 and 100/50 in Victron's SmartSolar range, offering 30A of charge current — enough for roof-mounted solar arrays up to 430W at 12V or 860W at 24V. Built-in Bluetooth means you connect directly to the free VictronConnect app with no dongle needed. The ultra-fast MPPT algorithm tracks the true power peak of your panels — important in partial shading conditions common when parked under trees or near buildings. Programmable load output with BatteryLife prevents battery over-discharge. Supports lithium (LiFePO4), AGM, gel and flooded lead-acid. VE.Direct port enables integration with Cerbo GX for remote monitoring via Victron's free VRM portal.

Frequently Asked Questions

How many solar panels can I connect to the SmartSolar MPPT 100/30?

The 100/30 suits up to 430W of panels in a 12V system or up to 860W in a 24V system. Panel open-circuit voltage must stay below 100V in the coldest conditions. For example, two 200W panels wired in parallel (each 22V Voc) gives 400W total — within spec for a 12V system. If you need more capacity, see the SmartSolar MPPT 100/50.

Does the SmartSolar 100/30 have Bluetooth built in?

Yes — all Victron SmartSolar controllers have Bluetooth built in. Open the free VictronConnect app on your phone and connect directly to monitor real-time solar input, battery voltage, charge current, and historical yield data. No dongle required. This is one of the key differences from the older BlueSolar range.

Is the SmartSolar MPPT 100/30 suitable for lithium (LiFePO4) batteries?

Yes — select the Lithium preset in VictronConnect and the controller uses the correct charge voltages (typically 14.2V absorption, 13.5V float for 12V LiFePO4). You can also set custom voltages. For a complete lithium campervan power system installation, see our lithium battery upgrade service.
